Rear Console Antenna
WARNING: This page is about a different car, the 2022 Buick Envision. However, it is still accessible from the selected car via links, so may be relevant.
This antenna is located in the rear of the center console.
The rear console antenna is used for vehicle starting functions. When the ignition mode switch is pressed, the antenna is energized or "pinged". This emits a low frequency challenge signal that is received by the keyless entry transmitter. The transmitter will then reply to this challenge with a response and, if correct, vehicle starting will occur.
